[SyncEvolution] Sync daemon must be started manually

Hello, I have installed Debian "Stretch" (version 9) and I have noticed that the syncevo-dbus-server is not launched at startup. If I "prime" it with a manual sync, then the subsequent automatic syncs indeed work. But how should I get the Syncevolution daemon to start automatically? I have compared with my old install, by I understand that the startup process is different now, and I can't reuse the startup helper script. TIA for any help - best regards, -- Daniel CLEMENT
